John Day

Most of the problems in the Internet today stem from its lack of a complete naming and addressing architecture. Not surprising, since this aspect of networking is not covered in any textbook. Most experts don't even know it is a problem. To get out of this morass, this talk will first consider the origins of the problem, the first realization of it (1972) and a solution (also in 1972), then explores the oft-cited Saltzer paper (1982) as pointing the way once a missing case is worked out. We will then consider the implications of a complete naming architecture, coming back to current events, consider what happens when practice is not kept close to theory by reviewing, the rejection of the right answer (1992), and how attempts to find a work around that rejection were based on the false distinction of loc/id split (1999) which then was brought to bear when the old problem (1972) reached crisis proportions (2006) and turned the Faber Marching Band down a blind alley, only to discover it had serious flaws (2008) and be inexorably dragged through a mass of patches that make it quite clear that all forms of IP are fundamentally flawed.


John Day has been involved in research and development of computer networks since 1970, when they were the 12th node on the "Net." Mr. Day has developed and designed protocols for everything from the data link layer to the application layer. Also making fundamental contributions to research on distributed databases,. He also did work on the early development of supercomputers and was a member of a development team on three operating systems. Mr. Day was an early advocate of the use of Formal Description Techniques (FDTs) for protocols and shepherded the development of the three international standard FDTs: Estelle, LOTOS, and extending SDL. Mr. Day managed the development of the OSI reference model, naming and addressing, and a major contributor to the upper-layer architecture; he also chaired the US ANSI committee for OSI Architecture and was a member of the Internet Research Task Force's Name Space Research Group. He was a major contributor to the development of network management architecture, working in the area since 1984 defining the fundamental architecture currently prevalent and designing high-performance implementations; and in the mid-1980s, he was involved in fielding a network management system, ten years ahead of comparable systems. Recently, Mr. Day has turned his attention to the fundamentals of network architectures and has published Patterns in Network Architecture (Prentice Hall, 2008), which has been characterized (embarrassingly) as "the most important book on network protocols in general and the Internet in particular ever written." Mr. Day is also a recognized scholar in the history of cartography, and published on 17thC China. Mr. Day has also contributed to exhibits at the Smithsonian and a forthcoming chapter in Matteo Ricci Cartographia.
